REHEATING AND FINISHING MACHINE FOR GLASS ARTICLES.

SPECIFICATION forming part of Letters Patent No. 608,427, dated August 2, 1898.

' Application filed January 11, 1898. Serial No. 666.353. (No model.)

residing at Jonesborough, in the countyof Grant and State of Indiana, have invented certain new and useful Improvements in Re heating and Finishing Machines for Glass Articles; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improved automatic warming-in or reheating and finishing machine for finishing glass articles; and the object is to' increase the efficiency and capacity of the machine.

To this end the invention consists in the construction, combination, and arrangement of the device, as will be hereinafter more fully described, and particularly pointed out in the claims.

The accompanying drawings show our invention in the best form now known to us; but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of our invention as set forth in the claims at the end of this specification.

The same reference characters indicate the same parts of the invention. I

1 represents the furnace, and 2 the reheating-chamber communicating therewith and having a longitudinal passage-way 3 open at its ends and bottom. This passage-way is curved longitudinally to a circle struck from the main operating-shaft 4, which is vertically journaled in suitable bearings and conin the path of said pinion.

tinuously rotated by any suitable means (not shown) in the direction of the arrow, as seenin Fig. 1.

5 represents a disk horizontally fixed 011 the Vertical shaft 4, and it is provided with a series of radial arms 6 6 and a similar disk 7, fixed on the same shaft below the disk 5, is provided with a corresponding series of .radial arms 8 8, which are vertically alined with those on the disk 5. As the entire series of arms 6 6 and the corresponding series of arms 8 8 and their working'parts are identical in construction and operation, we will now proceed to describe one set complete, which will answer for all. i

9 1O denote boxes fixed on the outer ends of the arms 6 and 8, in which'is journaled the vertical shaft 12, which has a rotary movement in said boxes in addition to a horizontal movement in its own plane concentric with the driving-shaft 4. 13 represents a pinion fixedon the lower end of said shaft, and it is adapted to mesh with the gearwheel 14, fixed on the counter-shaft 15, journaled in the bearing-box 1G, fixed on the arm 8, and the lower end of this counter-shaft is provided with a pinion 17, which meshes with the stationary segmental rack 18, fixed The upper end of the shaft'12 is screw-threaded, on which is detachably secured the horizontal disk 19.

20 represents theformer or plug,which supports the article while being finished, and it may be of any size and shape to correspond to the various articles adapted to be finished on a machine of this class. This former 2O encompasses the shaft 12, and it is detachably secured to a hub 21, formedwith a flange 22, having oppositely-disposed radial pins to engage the corresponding'orifices on the parallel jaws of the vertical rod 23, the lower end of which is pivoted in the outer end of the lever 24, fulcrumed in the preceding arm 8 of the series fixed to the disk 7. 25 represents a dog fulcrumed on said lever, and 26 denotes a set-screw extending through the lever and in contact with said dog to adjust the upward movement of the plug 20 with reference to the fixed disk 19. 27 represents an inclined rail fixed in the path of said dog,;which, as the dog rides over it, raises the lever rod 23, and former 20, so as to bring the upper edge ofthe latter in contact with the disk- 19.

28 represents a rectangular bar having a vertical movement in the alined boxes 29 30, fixed on the arms 6 and 8, and 31 denotes a raised rail fixed in the path of the lower end of said bar.

32 represents a radial arm supported horizontally by means of the boxes 33 Siand bracket 35 on the vertical shaft 4, the boxes resting on the collars 3U 36, fixed to the shaft, so as to permit the latter to rotate independently of said shaft, or, in other words, permit the arm 32 to move through the are of a circle independently of the rotation of said shaft.

37 represents a bar depending from the arm 32, its lower end terminating in a lateral toe which projects into the path of a corresponding toe on the bar 28.

39 denotes a bracket fixed on the outer end of the arm 32, and it is provided with a bearing-box 40, which is in vertical alinement with a corresponding box 41 on the arm 32 to receive the sleeve 42, journaled therein, and 43 denotes a cylindrical shaft extending vertically through said sleeve. ll: represents aspider fixed on the lower end of said sleeve, and the outer ends of its equilaterally-arranged arms 45 are formed with slots 47, in which are fulcrumed the buffer-levers l8, each one of which is provided with a V-shaped spring -19 to hold the pivoted shoe 50 on the lower end of said lovers in contact with the article being operated upon. The outer ends of the arms of the spider are formed with vertical lugs 51, in which are adjustably secured the thumb-screws 52, which project into the path of the upper end of said buffer-levers to limit their play in one direction. The shoes 50, which are pivoted on the lower end of the bu ffer-levers, are each formed with a dovetail groove to receive the buffer-block 53, and while these buffer-blocks 53 may be made of any suitable material we prefer to use a composition consisting of graphite and charcoal and a binding material, such as soluble glass or the like. This composition is pressed into blocks and then fitted to the shoes.

To do not wish to confine ourselves to the particular form of buffing mechanism, as it is evident that in some instances the buffer levers and blocks may be dispensed with and inverted conical cups used to encompass the article and accomplish the same purpose.

5. represents a double-flanged disk fixed on the sleeve 42, which engages the outer bifurcated end of the lever 55, fulcrumed in the vertical bracket 56, fixed to the arm 32, and the inner end of said lever is provided with an adjustable weight to counterbalance the weight of the sleeve and the parts carried by it.

57 represents a standard fixed to the base of the machine, and its upper end terminates in a lateral arm 58, on which is fixed an angular rail 59, which projects into the path of the duplex flanged disk 54, so as to depress the sleeve 42 when said disk comes in contact with said rail.

(J0 denotes a follower fixed on the lower end of the shaft 13, and 61 denotes a spiral spring encompassing the lower end of said shaft between said follower and the spider ti, and (J3 represents a collar fixed on the upper end of said shaft to limit its downward movement. The upper end of said shaft is square and extends through a corresponding orifice in the guide (it on the upper end of a standard 65, fixed to the outer end of the bracket This permits a vertical movement of said shaft and at the same time prevents it re volving in the sleeve. The sleeve 42 is provided with a longitudinal keyway 67, which receives a keyon the pinion (if), encompassing said sleeve, and which meshes with a corresponding pinion 70, fixed on the shaft '71, journaled in the bracket 30, and 72 represents a flexible shaft connected with the motive power and which imparts a continuous rotary motion to said sleeve and the bu ffjer-levers.

73 represents a spiral spring one end of which is connected to the arm 32 and the other fixed to a suitable point of the machine to restore the arm to its normal position after it has arrived at the forward limit of its movement.

The operation is as follows: \Vhen the shaft 4 is rotated in the direction of the arrow, the formers on the outer ends of the arms (5 pass through the entire length of the furnace 3, and while doing so the pinion 17 meshes with the segmental rack 18 during the passage of the former through the furnace, so as to rotate the shaft 12 at such a speed as will slightly fiare the article by centrifugal action when properly heated, thus permitting the insertion of the conical plug 20withouttouehingthe articleuntilthe plugis raised to its proper position at the point where the article leaves the furnace. The pinion 17 disengages the rack 18, discontinuing the revolution of the shaft 12 and allowing the article to settle around and about the plug 20, the buffers completing the operation, as before dccribed. It may be here stated that the polish is imparted to the article by the operation of reheating, the buffer-finishing being merely to restore the article to its original or desired shape, which is done by our improved composition buffers without destroying the delicate polish already imparted to the article by the reheating operation. A very important feature of the device is the divided former consisting of the supportingdisk, and the fact that it is frequently the case that where an article is finished on a solid or one-piece plug it will crack by contraction due to cooling before it can be removed from the solid plug. Assuming that the arm 6 has just withdrawn its former from the passage-way, the toe on the bar 28 comes in contact with the corresponding toe on the bar 27, thereby carrying the arm around 01-1 with it. At the same time the dog 25 on the lever 2t rides up on the rail 27, which carries the plug 20 up into the article, so as to engage IIO and support it at the same time the disk 54 on the sleeve 42 engages the fixed rail 59, which forces said sleeve, the spider 44, and the buffer-levers 48 downward, so that the buffer-blocks 53 encompass and rotate about the article to give it the required shape. The lower end of the bar 28 now rides up on the rail 31, which carries the toe on its upper end above the corresponding toe on the bar 37, so

as to release the arm 32 and permit the spiral spring 73 to restore the arm to its first position and ready to en gage the following formerarm as it withdraws its article from the fur nace. The lever 24 has in the meantime passed over the rail 27 and allowed the plug 20 to drop, leaving the finished article supported on the disk 19, from which it is removed and replaced by another article to be similarly treated, and the operation continued as before.

Having thus fully described our invention, what we claim as new and useful, and desire to secure by Letters Patent of the United States, is
